Effect of Different Rates of Liquid Trichoderma harzianum on Growth Enhancement of Tissue Cultured Abaca Seedlings

This study was conducted to evaluate the effect of different rates of liquid Trichoderma harsianum on the growth enhancement of tissue-cultured Abaca seedlings. There are six treatments replicated four (4) times with 5 samples per replication. The following were the treatment: T0-control, T1- 50 ml of L.T, T2- 40 ml of L.T, T3-30 ml of L.T, T4- 20 ml of L.T, and T5-10ml of L.T/liter of water. Based on the results, it did not successfully reject the null hypothesis on plant height, pseudostem girth, leaf count per plant, leaf area per plant, and the number of primary roots of Abaca seedlings treated with liquid Trichoderma harsianum. While the two parameters successfully rejected the null hypothesis, there is highly significant that developed greater lengths for their shoot and root lengths treated with liquid Trichoderma harsianum. When compared to the control, the use of Liquid Trichoderma harsianum can significantly increase abaca growth. Treatment 3 of Abaca seedlings with 30 ml of liquid Trichoderma harsianum was the most effective of the five treatments with this substance. The correlation between treatments and parameters is also favorable.
